[Bug c++/23160] New: ICE on m68k with -O3 but works with -O2

[treinen at debian dot org]

The file Ltl.C from the lbt program compiles with -O2 but compilation with -O3
throws an internal compiler error:

I forgot to say that this bug really seems to be m68k specific. On all other
architectures supported by debian GNU/Linux this compiled without any problem.

This works on the mainline with a cross compiler.

Neither reproducable natively with 4.0.2 20050726, appears to be fixed.
